Getting Started with Payroll

Running payroll might seem daunting, but with the right preparation and tools, any small business owner can manage it effectively. This guide walks you through everything you need to know to set up and run payroll for your business.

Step 1: Get Your Business Registered

Before you can run payroll, you need the proper registrations:

  • Employer Identification Number (EIN): Apply for one through the IRS. This is your business's tax ID for payroll purposes.
  • State tax registration: Register with your state's tax agency for income tax withholding and unemployment insurance.
  • Local tax registrations: Some cities and counties require separate registrations for local payroll taxes.

Step 2: Classify Your Workers

Proper worker classification is critical:

  • Employees vs. independent contractors: Misclassification can result in significant penalties. Use the IRS guidelines to determine the correct classification.
  • Exempt vs. non-exempt: Determine which employees are eligible for overtime pay under the Fair Labor Standards Act (FLSA).
  • Full-time vs. part-time: Define your thresholds and understand how they affect benefits eligibility.

Step 3: Collect Employee Information

For each employee, you need:

  • Completed W-4 form for federal tax withholding
  • Completed I-9 form to verify employment eligibility
  • State withholding forms as required
  • Direct deposit authorization and bank account information
  • Personal information including Social Security number and address

Step 4: Choose a Pay Schedule

Common pay schedules include:

  • Weekly: Every week (52 pay periods per year)
  • Biweekly: Every two weeks (26 pay periods per year)
  • Semi-monthly: Twice per month (24 pay periods per year)
  • Monthly: Once per month (12 pay periods per year)

Check your state's requirements — some states mandate minimum pay frequencies.

Step 5: Calculate Gross Pay

For each pay period, calculate gross pay:

  • Hourly employees: Hours worked multiplied by hourly rate, plus any overtime at 1.5x (or applicable rate)
  • Salaried employees: Annual salary divided by the number of pay periods

Step 6: Calculate Deductions and Withholdings

Deduct the following from gross pay:

Federal Taxes

  • Federal income tax (based on W-4 and IRS tax tables)
  • Social Security tax (6.2% of gross pay, up to the annual limit)
  • Medicare tax (1.45% of gross pay, plus 0.9% surtax for high earners)

State and Local Taxes

  • State income tax (varies by state)
  • Local taxes where applicable

Other Deductions

  • Health insurance premiums
  • Retirement plan contributions
  • Garnishments (if applicable)

Step 7: Calculate Employer Taxes

As an employer, you also owe:

  • Matching Social Security (6.2%)
  • Matching Medicare (1.45%)
  • Federal Unemployment Tax (FUTA) — 6% on the first $7,000 per employee, with credits for state payments
  • State Unemployment Tax (SUTA) — varies by state and your experience rating

Step 8: Run Payroll and Pay Employees

Once calculations are complete:

  1. Process payments via direct deposit or check
  2. Provide pay stubs to all employees
  3. Record all payroll transactions

Step 9: File Payroll Taxes

Stay on top of your filing deadlines:

  • Federal deposits: Semi-weekly or monthly, depending on your deposit schedule
  • Form 941: Quarterly federal tax return
  • Form 940: Annual FUTA tax return
  • State filings: Quarterly or annual, depending on your state
  • W-2s: Annual, due to employees by January 31

Why Most Small Businesses Use Payroll Software

While it is possible to do payroll manually, most small businesses find that payroll software pays for itself through:

  • Time savings: Automated calculations eliminate hours of manual work
  • Accuracy: Software reduces the risk of costly errors
  • Compliance: Automatic tax updates and filing reminders keep you compliant
  • Employee experience: Self-service portals and direct deposit improve satisfaction
